Deutsche Telekom spokesman Hans Ehnert said customers would be able to trade shares within 10 seconds and would have direct access to banks and stock exchanges.

The telecom giant's ISP, T-Online, is Europe's biggest with some 4.2 million customers. Last month Deutsche Telekom said it would launch an initial public offering of 10 percent of T-Online's share capital in mid-April.

T-Mobil, Deutsche Telekom's mobile phone arm, has roughly 16 million customers in Germany, Britain through One-2-One and Austria through Max.mobil. T-Mobil also has an additional three million customers in eastern Europe and Russia through a Russian subsidiary and joint ventures. Deutsche Telekom is also mulling an IPO of T-Mobil.

Ehnert said T-Mobil customers would also be able to book tickets for entertainment events such as concerts over their phones.

In Frankfurt trading shares of Deutsche Telekom dipped 1.35 euros, or 1.46 percent, to 91.15. In New York Deutsche Telekom's American depository shares rose 3/8 to 90.
